IMPROVEMENT IN THE MANUFACTURE OF FRUIT-CANS.

TO ALL WHOM IT. MAY OONOERN:

Be it known that we, CHARLES Brenna, Jon: A. Boss, and JACOB STEUEBNAGEL, all of the city and county of Allegheny, in the State of Pennsylvania, have invented'a new and usefulfl Improvementin Method of Constructing Fruit-Cans; and we do hereby declare that the following is a full and exact description thereof, reference being bad to the accompanyingdrawings, and to the letters'of reference marked thereon.

The nature of our inventionv consists in providing fruit-cans withan inner flange for supporting the lid, said flange being formed in one piece with the body of the can, by the method hereinafter described.

To enable others skilled in the art to make and use our invention, we will proceed to describe its construetien and operation.

In the accompanying drawings which form part of our specification- Figure 1 is a side elevation of our improvement in fruit-cans.

Figure 2 is a vertical section of the body of the can. 7

Figure 3 is a transverse section of the lid, and a vertical section of the body of the can, and represents the relation of the lid to the inner flange of the body of the can.

Figure 4 is a vertical section of the upper part of the body of can, and represents the method of forming the flange in one part with'the body of the can.

, In the drawings, A is the .body of the can; B represents the lid; C represents a flaring rim; D represents the inner flange, which is formed in one part with the body of the can. Theflaring rim 0 and inner flange D form a,V-sl1aped groove, (1, as clearly shown in figs. 2 and 3; In this groove is placed the drooping edgef of the lid B, as shown in fig. By means of the flaring rim C, inner flange D, drooping edgef of the lid, and V-shaped groove e, a recess is formed between the inner surface of the rim 0, and the outer surface of the lid 13, for the reception of sealing-cement. I

The method of forming the inner flange D is as follows: The body A- of the can, prior to furnishing it with its bottom, is grooved or corrugated, ,as represented at g, by means of ordinary grooving or swaging-tools. Then, by means of swaging-dies, the contour of which is clearly shown by the dotted lines 1: audit, the grooved portion 1 is swaged or otherwise formed into the shape represented at D, in figs. 2 and 3. By this method of forming the inner flange D, we form the flange in one piece with the body of the can, and thereby save the labor and trouble of soldering the flange 'D to the body of the can, and in every case wemake a close and surejoint, and a flange which iseven and uniform, having a rounded edge, which is a great desidcratum when cleaning out the cans.

By our method of providing cans"w.ith'the inner flange, we avoid the use of solder, (which is an alloy,)

which when brought in contact with the juice or liquid, and acid matter of the fruit, will injure both fruit and can.

We wish it clearly understood that we do not claim broadly an inner flange on fruit-cans; but 7 What we do claim asvot' our invention,.is I

The method herein described for formingand providing fruit-cans with an inner flange, for the purpose set forth.
